    Sammanfattning : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). LÄS MER

  2. 2. Internal Control : A study of concept and themes

    Detta är en avhandling från Heidelberg : Physica Verlag

    Författare :Olof Arwinge; Uppsala universitet.; [2012]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Internal control; Intern styrning och kontroll; Business Studies; Företagsekonomi;

    Sammanfattning : The concept of internal control has developed along with audit practice. As demands have been made for greater accountability in corporate governance, the significance of internal control systems in companies has increased. LÄS MER

  3. 3. Internal Control : A Study of the Concept and Themes of Internal Control

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Olof Arwinge; Linköpings universitet.; Linköpings universitet.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Economic Information Systems; Ekonomiska informationssystem;

    Sammanfattning : This thesis studies the accounting and auditing approach to control where the concept of internal control has developed along with the theory and practice of accounting and auditing and its stated objectives. In this context, internal control has traditionally been regarded as a means of ensuring financial reporting quality as well as a way of preventing and detecting fraudulent activity. LÄS MER

  4. 4. Towards Improved Control of TMP Refining Processes

    Detta är en avhandling från Chalmers University of Technology
